Problems solved by technology

The patent No. CN203314997U is a device for simulating a lever positioning technique, which realizes fixing the patient's lower limbs through the device to simulate the lever positioning technique, but the device can only keep the patient's limbs in a fixed shape, and cannot exert force at all, let alone accurately simulate the application of "smart". The impact on the lumbar spine, the effect of force application, and the changes in tissue have a large error compared with the actual situation.

Embodiment 1

[0027] Embodiment 1: The present invention provides a lever positioning technique force application device, which is used to apply force to the patient's body to simulate the lever positioning technique when the patient is lying prone. Its structure is as follows: figure 1 As shown, it includes: a bed board 1 for making the patient lie prone on it; a horizontally placed work-type, a pressing rod bracket 2 fixed on the bed board 1 by four uprights at four corners; The pressing rod 3 leaning on the patient's waist and the lifting frame 4 connected with the rear of the bed board 1 to lift the patient's lower limbs and stretch the waist backward.

[0028] Wherein, the pressing bar bracket 2 has two fixed beams arranged at a certain distance, connected by a beam in the middle, and the four corners of the rectangle formed by the two fixed beams are respectively provided with a column, which is fixedly connected with the side of the bed board 1 . There is an opening on the beam, and ...

Embodiment 2

[0036] Embodiment 2: This embodiment provides another kind of lever positioning technique force applying device, the difference between its structure and Embodiment 1 is: the structure of the pressing rod bracket is as follows Figure 4 As shown, the bottoms of two columns on one side are connected with the bed board 1 by a hinge 6, and the top can be opened. When the device is used, the two hinged uprights are opened, and the patient can more easily enter the inner space of the pressing bar bracket from the opened space, and after entering, the upright column is erected again to support the pressing bar bracket.

Embodiment 3

[0037] Embodiment 3: This embodiment provides another kind of lever positioning method force applying device. The difference between its structure and Embodiment 2 is that a scale value is set at the junction of the round rod and the sleeve on the pressing rod, and the scale value is measured in advance. The compression force exerted on the patient when the compression lever is compressed to this position. Therefore, various pressing forces can be conveniently and accurately observed or adjusted during use, and it is convenient to adjust and study the effects of different waist pressing forces.

[0038] For other structures and usage methods, please refer to Example 1.

Abstract

The invention relates to a force applying device for manipulation of lever location. The force applying device is used to apply force for performing manipulation of lever location on the body of a patient when the patient is in a prostrate position. The force applying device includes a pressing rod bearing against the back waist of the patient, a pressing rod support for installing the pressing rod and a lifting frame for lifting lower limbs of the patient to make the waist stretched backwards; a power mechanism is arranged on the lifting frame, and connected to a control end; the control end is used for controlling the power mechanism to drive the lifting frame to rotate around the hip position of the patient; the lifting frame is connected to a connecting rod, and the connecting rod is horizontally moved with the rotating of the lifting frame; and the pressing rod and the connecting rod are in transmission connection through a gear fixedly installed on the pressing rod support so as to make horizontal movement of the connecting rod drive the pressing rod to move in a vertical direction. The device can apply force to the waist and legs of the patient and simulate manipulation of lever location to do rapid pulling; and force applying situations can be more consistent with the actual force applied by doctors.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a lever positioning technique force applying device. Background technique [0002] The manipulation of lever location (manipulation of lever location) is a more practical technique for treating lumbar disc herniation. This manipulation acts on the lumbar disc herniation. First, expose the patient's waist, bend the knees and hips, and then cross the lower limbs. The olecranon of the right hand acts on the affected vertebrae of the waist, hold both ankle joints of the patient with both hands, and use the force arm lever to make the lumbar spine flex and extend, pull the lower limbs and ankles upward forcefully, when the puller lifts the lumbar spine over When stretching to meet a certain resistance, use "smart force inch strength" to make a quick pull. In order to study the mechanism of lever positioning manipulation and better improve its force application m...
